@smirffylover189, it depended on the fish. Some built theirs the night I brought them home, others waited for a few weeks. Sometimes they will build 4 huge ones in a row, and then stop building them for a while. It just depends!
@iamtetsuo, I swear your fish is Chance's twin! He's so awesome!
@diruak, thank you! I love him, he's such a silly fish. Very, very active and show-offy.
@everyone else! Thanks! I always feel warm and fuzzy when I see they build big ones, it makes me feel like I'm doing something right. :]

@smirffylover189, don't be too upset if he doesn't though! It's not your fault. They can be happy and not make bubble nests. Like I said, it just depends on the fishy!
@iamtetsuo, when I was looking at Bloodgore's pictures when you first put him up, I was like OMG they stole Chance! Because Chance has the red in his fins with the little white tips and the black head and everything, it's crazy
